this movie lasts a bit over 2 hours,
im coding it @755Kbit/s video bitrate - 576x304/25fps
cartoon mode,no B frames


the 3 SS are takes shortly one after the other,
the 1st looks ok
the 2nd is where i noticed a distortion
the 3rd is ok but one with iir "ghost effects"

i recoded the whole thing but had the same results
any feedback how to resolve this ?

The third image has a distortion caused by deinterlacing with blended fields and thus has nothing to do with xvid.

The second seems to have a small row of macroblocks misplaced.

Make sure those errors aren't within the source already please - if they're there already (do the same frame-by-frame check like you did on the xvid encode please) please report back.

Cheers

3rd picture:
tried field deint/blend...i cannot get rid of the ghosting...can live with that...

2nd picture:
i viewed the vob with vdubmod, and saw the source *is* indeed messed up...



ok,r lessons learned ... being too confident in the quality of some movies :rolleyes:
